The two singers join sister China Anne on an all-new episode this Friday!

In “chANTs of a lifetime,” Chyna is asked to join her favorite girl singing group, Trifecta (Sierra and Lauryn), but is sad to have to leave her friends and family behind.

With Chyna gone on a year-long tour, Olive (Sierra McCormick) and Fletcher (Jake Short) try to proceed as usual sans Chyna, and Lexi (Stefanie Scott) decides to put on another school musical where she’ll finally get to be the star,

JJJ recently chatted with Stefanie about the episode and dished, “It was really cool. They’re there almost every day anyway, but actually having them written into the show and we all get to be a part of it, it’s really neat. It’s a cool storyline to have in the show too. It’s a big two-parter. There’s a tour and stardom and it’s fun because it’s another chance for Lexi to have a fit.”
